What is the BROWNELLS - 79 DEGREE MUZZLE CROWNING CUTTER?

79 DEGREE MUZZLE CROWNING CUTTER

Hardened steel, muzzle crowning tool cuts a slight (11° less than square) target chamfer on barrels. Gives good rifling protection without going too deep. 90° - 11° = 79°, hence the name. Eight, precision-machined flutes give smooth, chatter-free cuts to help eliminate extra lapping or stoning. ¼"-20 thread fits Brownells muzzle chamfering handles. Use with our muzzle pilots to ensure precise alignment with your bore. Available in ½" and ¾" diameters to accommodate most rifle/handgun barrel diameters.



SPECIFICATIONS:

  • Material: Tool Steel
  • Length: 2-3/8"
  • Diameter: 1/2" or 3/4"

Perfect crowns
I had a grinding ball before and this cutter is superior to any grind ball to do barrel crowns.

Great tool
I just received the 90, 45, & 79/11 degree cutters. They all worked flawlessly.

Muzzle tools
The muzzle cutting tools and pilots worked great. That’s the kind of quality I expect from Brownells. The one problem I had was with the drill chuck adapter. The quarter by 20 threads would not except the cutters until I ran a tap in and out several times. After that everything worked great.

79* crown
Excellent product when used with the handle and brass pilot. Just go slow using cutting fluid and clean / check periodically.
